Sleepwalker — R.L. Stine

WELCOME TO FEAR STREET
Don't listen to the stories they tell you about Fear Street. Wouldn't you rather explore it yourself...and see if its dark terror and unexplained mysteries are true? You're not afraid, are you?

“Somebody -- help! Don't let me sleepwalk again!”
One week after she starts her summer job on Fear Street with old Mrs. Cottler, Mayra Barnes begins to sleepwalk. How terrifying to wake up outdoors in the middle of the night and not know where she is! Mayra becomes even more terrified when she discovers Mrs. Cottler may be a witch!

Is the old woman casting a spell on Mayra to make her sleepwalk? To add to Mayra's horror, she is being followed by a menacing stranger who seems to recognize her! But she's never seen him in her life!

Mayra's sleepwalking is leading her into more and more peril. She soon realizes she must take action. She must find out what is happening to her -- or she may never leave Fear Street alive!
